Divide (12n^3+8n^2-6n)/2n^2

1 answer:

8 0

$\frac{12n^{3} + 8n^{2} - 6n}{2n^{2}} = \frac{12n^{3}}{2n^{2}} + \frac{8n^{2}}{2n^{2}} - \frac{6n}{2n^{2}} = 6n + 4 - \frac{3}{n}$

LA BASE DE UN RECTANGULO ES 8 M MAYOR QUE LA ALTURA, EL AREA MIDE 65 METROS CUADRADOS ¿CUANTO MIDEN LA BASE Y ALTURA?

sp2606 [1]

Answer:

23 m and 15 m

Step-by-step explanation:

THE BASE OF A RECTANGLE IS 8 M GREATER THAN THE HEIGHT, THE AREA MEASURES 65 SQUARE METERS HOW MUCH DO THE BASE AND HEIGHT MEASURE?

Let the height of the rectangle is h.

Base = 8+h

Area of the rectangle, A = 65 m²

We need to find the base and height of the rectangle. The area of a rectangle is given by :

A = bh

So,

$65=(8+h)\times h\\\\65=8h+h^2\\\\h^2+8h-65=0\\\\(h-5)(h+13)=0\\\\h=5\ m\ \text{and}\ x=-13\ m$

Neglecting negative value, h = 15 m

Base = 8+15 = 23 m

So, the base and height of the rectangle is 23 m and 15 m respectively.

first person who answer correctly gets a brainllest The perimeter of a rectangle is 64 feet. The length of the rectangle is 3 ti

anastassius [24]

Answer:

2(3(8))+2(8)=64

Step-by-step explanation:

Here, w represents the width of the rectangle,

∵ length of the rectangle is 3 times the width of the rectangle,

So, length = 3w,

Since, the perimeter of a rectangle, P = 2(length + width)

= 2(w + 3w)

= 2w + 2(3w)

If P = 64 feet,

⇒ 2w +2(3w) = 64

⇒ 2w + 6w = 64

⇒ 8w = 64

⇒ w = 8

Verification :

P = 2(8) + 2((3(8)) = 16 + 48 = 64 feet

Hence, the first step that should be taken to verify that the width of the rectangle is 8 is 2(3(8))+2(8)=64

Note : a solution obtain from an equation is verified by substituting the value in the equation.

Segment AB is shown on the graph. Which shows how to find the x-coordinate of the point that will divide segment AB into a 2:3 r

GrogVix [38]

Answer:

$x=\dfrac{2}{5}\times (2+3)-3$

Step-by-step explanation:

The given ratio is 2:3.

x₁ = -3, x₂ = 2

We need to find the x-coordinate of the point that will divide segment AB into a 2:3 ratio. The formula is as follows :

$x=\dfrac{a}{a+b}(x_2-x_1)+x_1$

Put all the values,

$x=\dfrac{2}{2+3}(2-(-3))+(-3)\\\\=\dfrac{2}{5}\times (2+3)-3$

Hence, the correct option is (d).

3. You sell storm windows and doors. You receive a straight

OLEGan [10]

Answer:

$\$3886.8$

Step-by-step explanation:

Commission received on selling each storm window $=8\%$ of the selling price of each storm window

Commission received on selling each door $=12\%$ of the selling price of each door

Amount earned on selling storm windows = $5,400

Amount earned on selling doors = $28,790

Commission received on selling storm windows $=\frac{8}{100}(5,400)=\$432$

Commission received on selling doors $=\frac{12}{100}(28,790)=\$3454.8$

Therefore,

Total commission received $=432+3454.8=\$3886.8$
